FIG. 2 is a block diagram illustrating an example of a computer device according to at least one example embodiment. Each of the plurality of

electronic devices

110, 120, 130, and 140 or each of the

servers

150 and 160 may be implemented by a computer device 200 of FIG. 2 .

Referring to FIG. 2 , the computer device 200 may include a memory 210, a processor 220, a communication interface 230, and an input/output (I/O) interface 240. The memory 210 may include a permanent mass storage device, such as a random access memory (RAM), a read only memory (ROM), and a disk drive, as a non-transitory computer-readable recording medium. The permanent mass storage device, such as ROM and a disk drive, may be included in the computer device 200 as a permanent storage device separate from the memory 210. Also, an OS and at least one program code may be stored in the memory 210. Such software components may be loaded to the memory 210 from another non-transitory computer-readable recording medium separate from the memory 210. The other non-transitory computer-readable recording medium may include a non-transitory computer-readable recording medium, for example, a floppy drive, a disk, a tape, a DVD/CD-ROM drive, a memory card, etc. According to other example embodiments, software components may be loaded to the memory 210 through the communication interface 230, instead of the non-transitory computer-readable recording medium. For example, the software components may be loaded to the memory 210 of the computer device 200 based on a computer program installed by files received over the network 170.

The processor 220 may be configured to process instructions of a computer program by performing basic arithmetic operations, logic operations, and I/O operations. The computer-readable instructions may be provided by the memory 210 or the communication interface 230 to the processor 220. For example, the processor 220 may be configured to execute received instructions in response to a program code stored in a storage device, such as the memory 210.

The communication interface 230 may provide a function or a structure for communication between the communication apparatus 200 and another apparatus, for example, the aforementioned storage devices. For example, the processor 220 of the computer device 200 may deliver a request or an instruction created based on a program code stored in the storage device such as the memory 210, data, and a file, to other apparatuses over the network 170 under control of the communication interface 230. Inversely, a signal, an instruction, data, a file, etc., from another apparatus may be received at the computer device 200 through the communication interface 230 of the computer device 200. For example, a signal, an instruction, data, etc., received through the communication interface 230 may be delivered to the processor 220 or the memory 210, and a file, etc., may be stored in a storage medium, for example, the permanent storage device, further includable in the computer device 200.

The I/O interface 240 may be a device used for interfacing with an I/O device 250. For example, an input device may include a device, such as a microphone, a keyboard, a mouse, etc., and an output device may include a device, such as a display, a speaker, etc. As another example, the I/O interface 240 may be a device for interfacing with a device in which an input function and an output function are integrated into a single function, such as a touchscreen. The I/O device 250 may be configured as a single device with the computer device 200.

Also, according to other example embodiments, the computer device 200 may include a greater or smaller number of components than the number of components of FIG. 2 . However, there is no need to clearly illustrate most conventional components. For example, the computer device 200 may be configured to include at least a portion of the I/O device 250 or may further include other components, such as a transceiver and a database.

Hereinafter, a method and system for selecting and displaying a message in a messaging-based social network service according to example embodiments will be described.

FIG. 3 is a diagram illustrating an example of a component included in a processor of a computer device according to at least one example embodiment, and FIG. 4 is a flowchart illustrating an example of a message selection and display method performed by a computer device according to at least one example embodiment.

The computer device 200 according to the example embodiment may provide a message-based social network service through connection to an exclusive application or a website/mobile site. A message selection and display system implemented as a computer may be configured in the computer device 200. For example, the message selection and display system may be implemented in a form of a program that independently operates or may be configured in an in-app form of a specific application to be operable on the specific application.

Referring to FIG. 3 , the processor 220 of the computer device 200 may include a message selector 310 and a message display 320 as components that read instructions from the memory 210 to perform the following message selection and display method according to the instructions. Depending on example embodiments, components of the processor 220 may be selectively included in or excluded from the processor 220. Also, depending on example embodiments, the components of the processor 220 may be separated or merged for functional representation of the processor 220.

The processor 220 and the components of the processor 220 may control the computer device 200 to perform operations included in the following message selection and display method. For example, the processor 220 and the components of the processor 220 may be configured to execute an instruction according to a code of at least one program and a code of an OS included in the memory 210.

Here, the components of the processor 220 may be representations of different functions performed by the processor 220 in response to an instruction provided from a program code stored in the computer device 200. For example, the message selector 310 may be used as a functional representation of the processor 220 that controls the computer device 200 to select a portion of messages in a chatroom in response to the instruction.

The processor 220 may read an instruction from the memory 210 to control of the computer device 200 according to the instruction. The read instruction may include an instruction for controlling the processor 220 to perform the following message selection and display method.

Operations included in the following message selection and display method may be performed in order different from illustrated order. A portion of the operations may be omitted or an additional process may be further included.

Operations included in the message selection and display method may be performed by a client on which an exclusive application is installed. Depending on example embodiments, a portion of operations may be performed by the server 150.

The messaging-based social network service sorts and displays messages in order of a message transmission time in a chatroom. In the case of a chatroom in which anonymity is guaranteed or a large number of members participate, such as an openchat, a large number of new messages may be accumulated for a short period of time and, among them, a very limited number of messages may be actually useful to a user.

The example embodiments provide a function capable of selectively reading a useful message instead of the entire message stream delivered through the chatroom of the messaging-based social network service.

Referring to FIG. 4 , in operation S410, the message selector 310 may select a main message with high informational property from among unconfirmed new messages (hereinafter, unread messages) unread by a user as an incoming message in a chatroom. For example, the message selector 310 may select a message of which informational property is accredited based on reactions from other users participating in the chatroom. For example, the message selector 310 may select a message in which a positive reaction, such as like, mention, reply, comment, share, capture, and keep, from another user meets a predetermined (or, alternatively, desired) condition from among the unread messages as a main message. As another example, the message selector 310 may select a message including a keyword preset by a user as a message that is highly likely to be useful for the user in terms of informational property. At least one keyword the user is interested in may be preset through settings for the chatroom and the message selector 310 may select, as a main message, a message including a specific keyword set by the user from among unread messages. The message selector 310 may select the main message using a keyword that matches a category of the chatroom in addition to the keyword set by the user. As another example, the message selector 310 may analyze a conversation pattern in the chatroom, may extract a topic having a high topicality, and may select a message that matches the topic as a main message. The message selector 310 may extract at least one word talked about in the chatroom at an interval of a unit time and then determine a word that exceeds a certain level as a topic having a high topicality using a topic probability distribution for each message included in the chatroom. The message selector 310 may select, from among unread messages, a message including a keyword identical or similar to each topic as the main message. As another example, the message selector 310 may analyze a conversation pattern in the chatroom and may select, from among unread messages, messages that are exchanged as question and answer (Q&A) between other users as main messages.

The message selector 310 may select messages of different timestamps from among unread messages as main messages. Here, the message selector 310 may guarantee a predetermined (or, alternatively, desired) time interval between the main messages. For example, when selecting a subsequent main message, the message selector 310 may select the subsequent main message from among unread messages that elapse 5 minutes of a timestamp of a previous main message. The message selector 310 may guarantee a time interval of 5 minutes or more between a main message with a timestamp t(n) and a main message with a timestamp t(n+1). Here, n denotes an integer n>=0. Depending on example embodiments, the message selector 310 may guarantee a desired number of messages or more as a message interval between main messages. For example, the message selector 310 may select a subsequent main message from among unread messages that have skipped 100 messages after a previous main message. The message selector 310 may guarantee a preset number of intervening messages (e.g., 100 or more intervening messages) between two consecutive main messages (e.g., the main message with the timestamp t(n) and the main message with the timestamp t(n+1)).

The aforementioned main message selection process, that is, operation S410 may be performed on a client side. Here, the server 150 may select a main message according to a message selection method and may deliver information on the selected main message to a client.

In operation S420, the message display 320 may initially display main messages among unread messages at a time of entry into the chatroom in response to a chatroom entry request from the user. That is, instead of displaying all the unread messages when entering the chatroom, the message display 320 may initially display only a highly informational message determined to be interesting to the user. Here, the message display 320 may sort and display main messages in order of a time in which a corresponding message is received. As another example, the message display 320 may assign a priority to a message including a keyword set to the chatroom among main messages and may display the corresponding message at a top. As another example, the message display 320 may sort and display main messages in descending order of a number of specific reactions (e.g., share, reply, etc.) from other users. In addition, various sorting criteria may be used to display the main messages.

Subsequently, the message display 320 provides a function of expanding and reading unread messages based on a specific main message in response to a user request. When the user selects a single main message from among the main messages, the message display 320 may additionally display an unread message corresponding to at least one of a message received before the main message and a message received after the main message based on the selected main message. For example, the message display 320 may display an unread message after the main message selected by the user, that is, an unread message between the main message selected by the user and the subsequent main message. Here, the message display 320 may display a desired number of unread messages based on the main message. Depending on example embodiments, the message display 320 may display an unread message received within a desired period of time after the main message.

FIG. 5 is a flowchart illustrating an example of a process of displaying an unread message according to at least one example embodiment.

Referring to FIG. 5 , in operation S501, in response to a chatroom entry request from the user, the message display 320 may determine whether a number of unread messages corresponding to the chatroom the user requests to enter is greater than or equal to a desired number.

In operation S502, when the number of unread messages corresponding to the chatroom the user requests to enter is less than the desired number, the message display 320 may display the entire message stream corresponding to the unread messages. When the number of unread messages is less than the desired number, the message display 320 may sort unread messages in order of a message reception time at a time of entry into the chatroom and may display the unread messages in a normal view mode in which all unread messages are displayed.

In operation S503, when the number of unread messages corresponding to the chatroom the user requests to enter is greater than or equal to the desired number, the message display 320 may request the user to select a selective message view mode.

A process of selecting the selective message view mode may be omitted in the chatroom entry process.

When the user does not select the selective message view mode, the message display 320 may display unread messages in the normal display mode.

In operation S504, when the user selects the selective message view mode, the message display 320 may initially display only a main message stream selected from among the unread messages.

In operations S505 and S506, when the user selects a specific message from among the main messages, the message display 320 may display at least a portion of an unread message stream received after the specific message based on the specific message.

The message display 320 may select and display a useful message for the user from among unread messages accumulated in the chatroom and then additionally display unread messages before and after a corresponding message according to a user selection.

FIGS. 6 to 11 illustrate examples of a messenger interface screen executed on a client device that is an electronic device of a user.

FIGS. 6 and 7 illustrate a chatroom list screen 600 and FIGS. 8 to 11 illustrate a chatroom screen 800 in a selective message view mode.

Referring to FIG. 6 , the chatroom list screen 600 may be configured with a chatroom list 610 of all chatrooms created in a messenger.

In the chatroom list 610, chatrooms may be sorted and displayed in order of a recent message reception or transmission time.

Notification information

601 on an incoming message, that is, a received message may be displayed for each chatroom on the chatroom list screen 600. Here, the notification information 601 may include a number of unread messages to provide a notification for a message unconfirmed by the user.

The processor 220 may provide a selective message view mode for a chatroom including more than a desired number of unread messages among chatrooms each in which unread messages are present.

Referring to FIG. 7 , depending on example embodiments, to identify a chatroom that may be displayed in the selective message view mode, an item 711 indicating a chatroom including more than a desired number of unread messages in the chatroom list 610 may be displayed to be distinguished from items of other chatrooms.

When entering a chatroom in which a number of unread messages is less than a desired number in the chatroom list 610, the processor 220 may display the unread messages in a normal display mode. When entering a chatroom in which the number of unread messages is greater than or equal to the desired number, the processor 220 may display the unread messages in the selective message view mode.

Even for the chatroom in which the number of unread messages is greater than or equal to the desired number, the processor 220 may display unread messages in the normal display mode according to a user selection. In the chatroom entry process, the normal display mode may be selected as a mode for displaying unread messages. Alternatively, a switch to the normal display mode may be selected in the middle of displaying unread messages in the selective message view mode.

Referring to FIG. 8 , when the user selects, from the chatroom list 610, a chatroom in which a number of unread messages is greater than or equal to a desired number, the processor 220 may display the chatroom screen 800 in the selective message view mode.

In the selective message view mode, main messages 810 selected from among unread messages may be sorted based on a predetermined (or, alternatively, desired) condition and displayed on the chatroom screen 800. The main messages 810 may be sorted in descending order of a message reception time 811. Here, a message including a keyword set to the chatroom may be displayed at a top. As another example, the processor 220 may sort and display the main messages 810 in descending order of a number of reactions from other users participating in the chatroom, for example, a number of shares, or a number of “like” reactions.

Referring to FIG. 9 , depending on example embodiments, a “message sort (sort)” menu 901 that allows a user to directly select a criterion for sorting the main messages 810 may be displayed on the chatroom screen 800. The “message sort” menu 901 may include a sorting criterion 90 for sorting the main messages 810 on the chatroom screen 800. The processor 220 may sort and display the main messages 810 using the sorting criterion 90 selected through the “message sort” menu 901.

The processor 220 may display the message reception time 811 for each of the main messages 810 and may provide a drop-down menu 812 for displaying an additional unread message based on the corresponding main message 810.

The chatroom screen 800 in the selective message view mode may include a mode switching menu 801 for switching to the normal display mode for displaying all of the unread messages.

In the selective message view mode, the mode switching menu 801 may be displayed on the chatroom screen 800. During execution of the selective message view mode, the chatroom screen 800 may be switched to the normal display mode using the mode switching menu 801.

Referring to FIG. 10 , in response to a selection on the drop-down menu 812 of the specific main message 810 on the chatroom screen 800, the processor 220 may display additional unread messages 1020 based on the corresponding main message 810.

The additional unread messages 1020 expanded and displayed through the drop-down menu 812 may correspond to, for example, messages received after the main message 810. In response to a selection on the drop-down menu 812 of a timestamp t1 message (hereinafter, t1 message) among the main messages 810, the processor 220 may additionally display an unread message received between the t1 message and a t2 message. Here, the processor 220 may display a desired number (e.g., 10) of messages received after the t1 message or may display a message received within a predetermined (or, alternatively, desired) period of time (e.g., 5 minutes) after the t1 message among unread messages received between the t1 message and the t2 message. Depending on example embodiments, the processor 220 may display a message of a common conversation topic among the unread messages between the t1 message and the t2 message, that is, may additionally display a message that is received after the t1 message and of which conversation topic is not changed.

In a state in which the additional unread messages 1020 are displayed based on the main message 810, the drop-down menu 812 may be switched to a collapsed menu 1022 for processing the additional unread messages 1020 to be hidden.

Referring to FIG. 11 , the processor 220 may differently display a display element (e.g., a color or a shape of a speech bubble, a text color, etc.) of a message user interface (UI) 813 for each of the main messages 810.

When displaying the additional unread messages 1020 based on the main message 810, the processor 220 may display the unread messages 1020 through the same message UI 1020 as the message UI 813 of the main message 810. That is, the processor 220 may display the main message 810 and the additional unread messages 1020 provided based on the main message 810 through the

message UI

813, 1023 in a unified style. Displaying messages through a message UI in a unified style may include displaying at least one of a shape or a color of a message speech bubble, and a text color, a font, and a shadow of a message in the same manner.

It is possible to initially display the main message with high informational property among unread messages in the selective message view mode and then to selectively expand and display an additional unread message based on the main message 810.

According to some example embodiments, it is possible to implement a new method of a message display mode by selecting and displaying a useful message for a user among unread messages in a chatroom. As a selective message view mode, it is possible to provide a function capable of initially reading a message with high informational property among unread messages and a function capable of selectively expanding and reading unread messages based on a specific main message.
